STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREE PLAY
(a) Stop the vehicle and face the tires straight ahead.
(b) Gently rock the steering wheel up and down with a finger,
and check the steering wheel free play.

(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR±12).
(c) Start the engine and run at idle.
(d) Measure the steering effort in both directions.
Steering effort (Reference):
4.9 N´m (50 kgf´cm, 43 in.´lbf)
HINT:

REPAIR PROCEDURES
HINT:
This is the repair procedure for steering off center.
1. INSPECT STEERING WHEEL OFF CENTER
(a) Apply masking tape on the top center of the steering
wheel and steering column upper cover.
(b) Drive the vehicle in a straight line for 100 meters at a
constant speed of 35 mph (56 km/h), and hold the steer-
ing wheel to maintain the course.
(c) Draw a line on the masking tape as shown in the illustra-
tion.

(d) Turn the steering wheel to its straight position.
HINT:
Refer to the upper surface of the steering wheel, steering spoke
and SRS airbag line for the straight position.
(e) Draw a new line on the masking tape of the steering wheel
as shown in the illustration.
(f) Measure the distance between the 2 lines on the masking
tape of the steering wheel.
(g) Convert the measured distance to steering angle.
Measured distance 1 mm (0.04 in.) = Steering angle
approximately 1 deg.
HINT:
Make a note of the steering angle.
2. ADJUST STEERING ANGLE
(a) Draw a line on the RH and LH tie rod and rack ends where
it can easily be seen.
(b) Using a paper gauge, measure the distance from RH and
LH tie rod ends to the rack end screws.
HINT:

Measure the RH side and LH side.

Make a note of the measured values.
(c) Remove the RH and LH boot clips from the rack boots.
(d) Loosen the RH and LH lock nuts.
(e) Turn the RH and LH rack end by the same amount (but
in different directions) according to the steering angle.
1 turn 360 deg. of rack end (1.5 mm (0.059 in.) horizon-
tal movement) = 12 deg. of steering angle
(f) Tighten the RH and LH lock nuts.
Torque: 55 N´m (560 kgf´cm, 41 ft´lbf)
NOTICE:
Make sure that the difference in length between RH and LH
tie rod ends and rack end screws are within 1.5 mm (0.059
in.).
(g) Install the RH and LH boot clips.
